In 2013 Saito happened across his first digital currency case and it would change the course of his work. During Mt. Gox's bankruptcy, Saito had the opportunity to work with the government discussing regulation of Bitcoin.

Since then he's also been a legal advisor to the Japan Blockchain Association, a corporate auditor of Topaz Capital, a corporate auditor of Mitsubishi Jisho logistics REIT, and a director of Cedyna Servicer.
